hair removal suggestions

ok so I had been having problems down there with these reoccuring painful bumps for a while and I didn't know what they were so I got worried and begged my mom to take me to a gynecologist because I didn't think it was normal(I'm 15 and I don't know too much about how to shave right or what certain things look like down there)so when I went to the doctor she told me that I had those bumps from shaving and that I should put Neosporin on them to heal...the problem is she also told me to stop shaving and just be natural,but I hate having hair down there and I don't want to gross a boy out when I become sexually active or if someone wants to finger me so I need some suggestions on how to shave right or a different way of removing hair without getting those bumps again
